Abstract
Fatigue is one of the most important failure modes of fibre-reinforced composites. In this paper, a new fatigue failure theory for multidirectional fibre-reinforced composite laminates is developed, by combining the interaction residual strength and interaction residual stiffness models with the recently improved Puck's failure theory [Dong, Wang and Karihaloo, 2014, Composites Science and Technology] which includes the in situ strength effect. This fatigue theory can predict both the fatigue life and residual strength of fibre-reinforced composite laminates under multidirectional loadings, with consideration of the gradual degradation of strength and stiffness of the laminate. The theoretical results are in good agreement with available experimental results [Kawai and Honda, 2008, International Journal of Fatigue].
